It may be old thinking but to my mind its still good thinking...
what a bard or chanter can give a group:
CC - if you have a necro or SK or ranger or monk this is nice but not needed.
I box SK, mage, bard and the wife plays her wiz. Even with the SK having the bard pull is so much easier. And you seriously underestimate the value of CC but of course you do you are level 75 according to your other post.
Mana regen - one word "potions"
I would LOVE to see a potion thats even comparable to my bards hp/mana regen songs. One other thing if you play SK or necro (which it seems you do) potions do not stack with our lich line bard songs do (not sure on chanter buffs but i assume they do as well).
DPS - can provide a significant dps increase
The difference being shamans provide significant buffs to melee, bards and chanters provide significant buffs to all classes. The buffs that bards bring to casters are massive, the buffs they bring to melee is better than shamans.
Bards have effortless AOE slow. I know shamans have AOE slow but with bard just put it in /melody and you're good to go.
what a sham can give a group
CC - With Virulent paralysis and root you can take care of a couple extras.
Yes, a 2 minute cooldown root, thats your answer to CC.
Buffs - there is no class with buffs that can touch a shaman and i dont like running to the guildhall for buffs every 2 hours then wasting my buffs running back to camp.
No, there is no class that can touch the buffs of bards. Shamans are good buffers bards are better... The only thing people stick to is unity which is very overrated.
DPS - for melee toons or casters with a melee pet the shaman can boost dps alot with his panther line of spells and haste, also with a couple aa spent the dot ticks are sick.
Again for pure melee groups its an easy choice, shaman. But for "casters with a melee pet" like you said the bard wins hands down. A mage pet should only be 40% tops of the mages DPS with a shaman you are ignoring 60% of the DPS with a shaman over bard. With necro its 20/80 at most and you are ignoring the main cause of the DPS.
Just looking at your group in the other thread you posted in. Nec, Mage, shaman with a healer merc. If you are not even using the shaman to heal in that group its a wasted group slot as far as im concerned.
You do realize that bards have a proc line as well right and its better than the panther line... Bards can take you to the haste + overhaste cap and shamans cant.

That blows away any buffs your shaman can bring to the table, has slow and buffs healing.
So yes like i said its old thinking... Shamans are not even the best melee buffers anymore and have not been in quite a while. Bards melee buffs are better than shamans, bards caster buffs are massive.
Bards buff healing by 10% and the same song adds huge mana/hp regen. Bards buff melees haste all the way to OH cap, 38% to triple attack chance, 6% flurry, flurry added specifically to pets, increase the minimum damage of skills by 35% and increase skill damage by 4%. 28% increase in spell damage and a better proc buff than the panther line that so many people keep bringing up...
Add in 50% slow and thats just MY /melody setup.
So again enough with the old thinking. Shamans have not been the kings of melee buffing for years. Its time to stop with the automatic answers from years gone by and actually do some homework. Bards buff melee damage much better than shamans do these days, they buff caster DPS better than anyone these days. Bards are literally THE BEST BUFFER IN THE GAME.
And in direct response to you. Your group is nec, mage shaman and you use a cleric merc. Look at the songs i linked that i use and tell me what your shaman does better? Slowing is it...
Im not saying if you play a shaman you are bad or anyone should change their ways. My frustration comes from being in game and seeing people ask what to add to a group and people saying shamans are the best. Even last night, someone asked "I have a mage and a wizard what should i add" first 4 responses where shaman!
